Support multiple test names in /create-issue and fix underscore escaping in titles

[Copilot]

Description

The /create-issue command only supported a single test name per invocation, and issue titles contained unnecessary backslash-escaped underscores (e.g., Exec\_NginxContainer\_ListFiles) because EscapeMarkdownInline was applied to titles, which are plain text, not markdown.

Changes

• JS parseCommand: Returns testQueries array. Accepts multiple --test flags and multiple positional args. Keeps testQuery (first element) for backward compat.

  /create-issue TestA TestB TestC
  /create-issue --test TestA --test TestB --test TestC
  /create-issue TestA TestB https://github.com/.../pull/123
  

• Workflow YAML: Extract step outputs test_queries JSON array. Resolve step loops via jq, producing indexed result files. Create/update step processes each result independently and posts a combined summary comment.
• C# title fix: Removed EscapeMarkdownInline() from issue title in CreateIssueArtifacts — GitHub issue titles are plain text.
• Tests: 3 new tests for multi-test parsing; existing tests updated to assert testQueries array.

Mixing positional names with --test flags remains rejected as ambiguous.
